O 9.0 x 10^3 N/C directed towards the negative charge O 9.0 x 10^3 N/C directed towards the positive charge O The net electric field is zero. O 2.3 x 10^3 N/C directed towards the positive charge O 2.3 x 10^3 N/C directed towards the negative charge

Determine the magnitude of the electric field.

What is the magnitude of the electric field at a point directly midway between the two balls? 2.22×103 N/C 542 N/C 103 N/C 530. N/C

A small, m = 7.50 g plastic ball is suspended by a 20.0 cm long string in a uniform electric field as shown in the figure below. If the ball is in equilibrium when the string makes a 15.0° angle with the vertical, what is the net charge on the ball? μc E 1.00 x 10N/C 15.0 20.0 cm Ⓡ

A small 2.25 g plastic ball that has a charge q = 1.35 C is suspended by a string that has a length L = 1.00 m in a uniform electric field, as shown in the figure. If the ball is in equilibrium when the string makes a 0 = 9.80° angle with the vertical, what is the electric field strength E? E = N/C | Ē

A 0.4 g object is placed in a 449 N/C uniform electric field. Upon being released from rest, it moves 62 m in 1.8 s. Determine the object's acceleration & charge magnitude. Assume the acceleration is due to the E-field (i.e., ignore all other forces). a = Q =
